"Thank you for your email regarding the quality of the text in your
Barnes & Noble eBook, "Influencer". Please accept our sincere apologies
for any inconvenience this may have caused.

Because this file is provided by the publisher, we are forwarding your
feedback to them for review. You can change the Font and Size format for
your ebook display, but unfortunately, you cannot change the centered
text to left justified, as the format is the way the publisher has
presented it.

As stated on our website, Barnes & Noble eBooks cannot be returned and
are non-refundable once they have been downloaded to a computer or
device. Our records show that your eBook was successfully downloaded
after purchase."

If the publisher doesn't respond, I would de-DRM it, and re-author the book.

I tried to re-author the book using Sigil. The left justification worked. However, the first letter of every paragraph became its own paragraph. I'm not patient enough to go through the entire book to fix that. And I am not adept enough technically to figure out an automated fix. So, I have put that book away for now and will wait to see if the publisher comes up with anything soon. If not, I will do my best to stay away from that publisher.

Don't let them smokescreen you with that crap. If you bought a defective book, they owe you a credit. They can de-authorize it easily (thus removing it from your possession), and you have email proof that they have acknowledged there is a problem. Kick it up the chain. Go to consumerist.com and search for EECB (Executive Email Carpet Bomb) and find instructions on how to send one. Be sure to CC: tips@consumerist.com. B&N won't want the bad PR, and will probably not only refund the $20, but give you an extra $20 for bringing the problem to their attention. Don't let them get away with it. Use the internet for the power of good!

I wholeheartedly agree. You should also let B&N know this is a severe disadvantage to using them over Amazon/Kindle, as Amazon reacted to similar complaints about bad formatting from Kindle owners a few months ago and now allows for eBooks to be returned up to 7 days after purchase for issues such as this one. This is definitely one advantage Kindle has in the marketplace over the nook.
